Time Machine 2tb limit?
Hi! I tested the ReadyNAS Pro equipped with 6tb. We (ad agency) are planning to use it with TimeMachine to backup our desktop macs. I wanted to use the maximum capacity, which is 4607GB, for TM, b...

It may just be a naming issue still. One way to double check is to point TM to a standard share on your nas without any pre-prepared sparsebundle and then start a backup job. This may fail but IIRC TM does *try* to make the sparsebundle and you will see this and the name that is used.
As a test I pointed one of my machines (10.6.2) to a new share and kicked off a TM backup. In the past this would fail as TM cannot make the sparsebundle, but interestingly under the 4.1.7 beta firmware the sparsebundle was created just fine. (note I'm using an NV+, not a pro)
I stopped the backup and, instead of creating a sparsebundle, used terminal & resized the TM created sparsebundle to 4TB
I verified the size by mounting it before kicking off a backup job which then seemed to work fine, though I can't properly test this as I don't have an easy way to generate the backup data needed, nor the time.
But in principle it looks like it is possible to manually create a sparsebundle larger than the current Frontview limits

hdiutil resize -size 4T <sparsebundle>
